summary:Web-based systems for construction-related tasks do not always simultaneously reflect the expectations of their developers and users. There is no consistent methodology to measure the level of agreement between the user’s expectation and the actual performance of a given web-based systems. To illustrate this, the differences in perception are assessed with respect to a system aimed at expediting the approval process of reinforcing steel bars. The expectations and the performance of the system are analyzed based on data obtained from structural designers, contractors and rebar suppliers. The paper shows how to specify the relationship between perception and actual performance of the system developed by the authors for the approval process of reinforcing steel design and estimation. Using quantitative methods, these relationships will be categorized with respect to the type of organization, prevailing type of construction and use of CAD components extracted from historical designs of similar structures. The difference in expectation and satisfaction from the performance of the system is analyzed and its potential impact on system’s re-design is elaborated.
